@GoodCubanito ..... @Babin Farms ......refers you to a good thread. If not using the boat over the Winter the batteries may actually be harmed (sulfated) by being on a trickle charger, so beware! There is comprehensive information on this forum on the topic you require!
@212s ..... @jEt_jAk ..... @Neutron ..... @AZMark ......agree with all the great suggestions. I have the Noco and love it. When not using my batteries for a long time (say over the Winter lay-up) I would charge them at Fall decommissioning, store them in a warm place then charge them in the Spring before use. I have never had a problem doing this. Since 2014 I have been using AGM TPPL. You charge them in the Fall and they lose so little charge over the Winter that they will fire-up the boat at recommissioning without a Spring charge although I do use an intelligent multi stage charger for my Spring recommissioning. To me "trickle charging over the Winter has so much potential for battery damage (sulfation, plate damage, off gassing etc.) and no apparent up-side, why would I do it?
@Neutron ..... aha.... the "I use my stuff all year round" is the game changer for the answer. If the battery is disconnected in the late Fall for a Winter lay-up and not used until Spring IMO putting it on a charger would be harmful to it.
BTW .....lucky you - the all year round use!
I did this practice even when i lived in Rhode Island.@Neutron ..... aha.... the "I use my stuff all year round" is the game changer for the answer. If the battery is disconnected in the late Fall for a Winter lay-up and not used until Spring IMO putting it on a charger would be harmful to it.
@Neutron ..... first no argument as I certainly recognize your right to your opinion and you will do what you deem best and so will I - just a respectful discussion. My opinion is that there is no chemical reason to continuously charge "modern" batteries if they are not being used - even sporadically. Even older style chemical batteries can be more easily damaged by trickle charging than by just leaving them alone. Charge them store them and charge them again after storage - if you want to n- mor just connect and go. Modern chemistry batteries, for example AGM and AGM TPPL do not need ANY kind of "trickle" charging. Actually "trickle" charging is NOT what modern chargers do anyway as "trickle" charging refers to a practice from at least 15 years ago that led to a lot of sulfated batteries and batteries whose ability to hold a charge continually declined. So the word "trickle" itself is not accurate. There is a wealth of information available on this topic available on the internet. I had Series 4 AGM batteries on a 2013 cruiser I had. Disconnected them in October connected them in May put the cruiser in and they fired-up twin 350 Mercruiser Magnum engines (electronically ladened) first try and showed full charge - that was without even re-charging them. In 2014 I bought a bigger cruiser with 6 AGM TPPLs - same thing except they fired-up twin High Performance 502 mercury Magnum engines (super ladened with electronics) - first try. BTW both of these boats were in enclosed but not heated storage - not freezing but not heated - so the batteries were "cold" all Winter. As for my opinion -my info comes from lengthy and repeated experience (several decades), numerous discussions with engineers at Penn Deka and Northstar and a relative who is a chemical engineer and boating enthusiast. My question is - unless a person's batteries were old technology (older series 24 flooded) why would anyone storing (not using) their batteries risk damaging them for no reason?
@JBehrens ....ProMariner makes superb products. I had the chargers and galvanic isolators manufactured by them on a 2013 32 foot cruiser with 4 AGM batteries and on a 2014 38 foot Cruiser with 6 AGM TPPL batteries.
